| 摘要 | An aluminum alloy for casting-forging, which consists essentially of 0.6 to 1.8 mass % of silicon, 0.6 to 1.8 mass % of magnesium, 0.8 mass % or less of copper, 0.2 to 1.0 mass % of manganese, 0.25 mass % or less of chromium, 0.0 to 0.15 mass % of titanium and inevitable impurities; and an aluminum cast/forged article manufactured by the casting-forging of the above alloy. The above article exhibits improved mechanical properties such as tensile strength, offset yield strength and elongation over conventional articles, when used as an aluminum part for an automobile such as a part of a suspension, a frame or a part of an engine, and also can be manufactured at a low cost. | ||||||
